Grid system being ignored

[jamessmythe]

Hi David,

I am trying to lay out a set of cards as follows...
tablerDashBody(
tablerCard(title = "Title", width = 6, status = "red"),
tablerCard(title = "Certificate", width = 3, status = "orange"),
tablerCard(title = "Year", width = 3, status = "yellow")
)

The cards render one above the other, instead of side by side. Am I missing something please?

Thanks,
James
